To consider the diverse ways people can be part of missions, see the free video series, 6 Ways to Reach God’s World (OMF and Perspectives).
Some of the most popular free, inspirational videos on mission topics can be found in the HistoryMakers collection.
Check out Moving Works, a media ministry that exists to create videos lifting up Jesus and God’s work around the world.
Many mission agencies create videos. While some of the videos describe the agencies and their work, others are of more general interest. See, for example, the video streams for Wycliffe, OMF, Pioneers, and OM USA.
